DRAFT ARM FOR DISPENSING BEVERAGES Filed July 8, 1936 fi'iiiiiiiiiiiiiiiiiii J6 L9 65 J9 EW'" "Hull/HUME Patented a... 13, 1939UNITED STATES PATENT OFFICE 14 Claims.

In my prior patent, No. 1,525,650, granted February 10, 1925, Idisclosed a novel draft armfor dispensing beverages. The presentinvention has for its object to improve the draft arm of that 5. patent.

One of the improvements contemplated by the present invention is toprovide a novel construction and arrangement, whereby an operatinghandle that swings from and toward an operator 10 standing in front ofthe dispenser may be utilized.

A further improvement is to provide a novel movable stop device for theoperating handle to permit a different manipulation of the handle whenthe stop device is in one position than when it is in another position.

Another improvement is so toconstruct the apparatus that all of it,except the operating handle, may be mounted within the cooling re- 20ceptacle for the liquid with which a syrup or the like is to be mixed;the parts of the draft arm being so organized that a simple straightdischarge nozzle shall project through the bottom of the main receptacleof .the dispenser close to 5 the front wall thereof, so that theattendant can readily place a glass or cup under the nozzle and, withoutdifiiculty, observe the filling thereof.

Another improvement consists in simplifying what may be termed thecasing of the body of the draft arm, including the nozzle, whereby themain part of the draft arm may be disconnected while the nozzle remainswithin the dispensing receptacle; whereby the nozzle serves as a supportfor the main portion of the draft arm and 35 is adapted to be easily andquickly secured thereto or detached therefrom; and whereby access mayreadily be had to the working parts for inspection, cleaning and repair.

Another improvement consists in the delivery into what may be termed thedispensing chamber associated with the nozzle, at low pressure, of aliquid which is supplied at high pressure.

Still another improvement consists in so organizing the working partsthat liquids may be 45 permitted to flow freely from the syrupcontainer, through the draft arm, and be discharged at the nozzle, forany desired length of time, for the purpose of draining the syrupcontainer or flushing out and washing the latter and the draft 50 arm asa whole.

Another improvement consists in providing for a rapid and effectivecooling of syrup.

The various features of novelty whereby my invention is characterizedincluding, among 55 others, the improvements heretofore specificallymentioned, will hereinafter be pointed out with particularity in theclaims; but, for a full understanding of my invention and of its objectsand advantages, some of which have already been enumerated, referencemay be had to the follow- 6 ing detailed description taken in connectionwith the accompanying drawings wherein:

In the drawings the draft arm apparatus is shown as comprising acontainer 1 for syrup, a casing 2 which houses the valve mechanisms andmeasuring means for liquids to be dispensed, and a nozzle 3 throughwhich the liquids are discharged. This apparatus is housed within asuitable receptacle A, close to one wall of the latter, to which I shallrefer as the front wall; and the nozzle extends through and projectssomewhat below the bottom wall of the receptacle. The operation of thedraft arm is controlled by a lever or handle 4 disposed on the outerside of the receptacle and adapted to swing in a vertical plane from andtoward said front wall of the receptacle. The nozzle, which is separablefrom the casing 2, is shown as being provided with a wide, deep,vertical flange 5. The casing fits against the top of the nozzle properand against the flange, so that the casing and the nozzle may be rigidlyfastened together and, at the same time, be easily separated from eachother. This arrangement permits the nozzle to be secured permanently inthe receptacle, and the casing to be quickly and easily removed, withoutdanger that the casing will not be properly positioned when againreturned to the receptacle.

The casing, as in the aforesaid patent, contains a frusto-conical valvechamber or receiving chamber 6 whose major axis is horizontal, togetherwith a measuring chamber 1 underlying the valve chamber. Communicationbetween these two chambers, as best shown in Figs. 5, 8, 15 and 16, isthrough a long port 8 in the top wall of the measuring chamber, andextending lengthwise of the latter. Within the valve chamber is anelongated cup-shaped plug valve 9 having a wall thereof and a long port,II] which in some positions of the valve registers with the port 8. Thevalve chamber is also provided with an outlet I2 through the top thereoffor the escape of air. Normally this outlet is closed by the plug valve.However, in one position of the valve, as shown in Fig. '15, this outletis placed in communication with the port 8 by a passage I3 in a memberI4 which extends diametrically across the interior of the plug valve;thereby placing the measuring chamber directly in communication withatmosphere.

The plug valve is encased in a sheathing I5 so that the body of thevalve may be made of any desired material and yet have the best possiblebearing against the surrounding wall of the valve chamber.

In-draft arms of this kind it is desirable to maintain an air cushionwithin the upper regions of the plug valve. In order to accomplish thisin such a way that the air is not afforded an opportunity of leaking outthrough a joint, I provide the plug valve with an internal flange or lipI6 'near the open end of the cup; this lip or flange being so disposedthat it lies at the top when the valve is in its normal position whichis that illustrated in Fig. 8; thereby forming with the wall at theclosed end of the cup and a portion ofthe longitudinal wall of the cup apocket the walls of which contain no joints.

A feature of the present invention has to do with the flow of air in onedirection and syrup in the other direction, between the valve chamberand the syrup container. In the arrangement shown, the open end of thevalve chamber is connected to the bottom of the syrup container by anelbow II of large diameter; the internal diameter of the elbow beingpreferably about the same as that of the valve chamber. One arm of theelbow, as best shown in Figs. 2 and 3, stands upright and communicateswith the interior of the syrup container through an opening I8 in thebottom wall of the container; this opening being much smaller indiameter than the diameter of the elbow. In an actual commercial form ofmy draft arm, this opening is about three-eighths of an inch indiameter. When the plug valve is turned so as to place its port inregistration with that in the top of the measuring chamber, assuming themeasuring chamber at the time to be filled with air, syrup within thevalve chamber flows down into the measuring chamber, displacing the airin the latter. The displaced air rises from the measuring chamber intothe valve chamber, and from there bubbles up through the elbow and intothe syrup container. Syrup flowing down into the measuring chamber fromthe valve chamber is supplied through a conduit I9 connected at one endto the bottom of the syrup container. The other end of the conduit I9 isconnected to the lowest point of the elbow I'i, so that syrup can flowthrough the conduit into the bottom of the elbow. The internal diameterof the conduit I9 is preferably greater than the diameter of the openingI8. In actual practice, while the measuring chamber is being filled, theescaping air leaves in the form of bubbles, such as indicated at B inFig. 3; each bubble of air being pushed upward by a correspondingquantity of syrup descending from the container through the conduit I9.

The conduit I9 serves not only to deliver syrup to the controlling anddispensing mechanism, but also as a cooler for the syrup. When the syrupcontainer is first filled with syrup, the latter may be warm and requireconsiderable time to become chilled while remainingin the container. Imake the conduit IQ of considerable length so that it serves as acooling coil whose contents are rapidly cooled by the refrigerant withinthe receptacle. Consequently, almost as soon as warm syrup is introducedinto the container and flows down into the conduit or cooling coil tofill the latter, a substantial quantity of syrup becomes chilled and isready to be dispensed.

It is the intent that when the operating handle of the draft arm ispulled forward or outward, the syrup shall be emptied from the measuringchamber, as in my aforesaid patent, and be mixed with soda water underpressure. It is desirable to permit the entire contents of the syrupcontainer to be drained and the container and the remaining portions ofthe draft arm that come in contact with the syrup and other liquid to beflushed. I have accordingly provided means whereby, upon pushing thehandle rearwardly beyond its neutral position, the valves which con trolthe syrup are opened without disturbing the Valve that controls the sodawater.

In addition to the plug valve 9, there is a second valve 2I forcontrolling the syrup. The

valve 2| is an upwardly-seating member below the measuring chamber andadapted when raised to close a large outlet 22' through the bottom wallof the measuring chamber. The valve has a tubular stem 23 extendingentirely through the same; the upper end of the stem being open and thelower end having secured thereto and being closed by a solid downwardextension 24. The upper part of the stem 23 is adapted to slidelengthwise in a bore or passage 25 in the wall of the casing 2, into thevicinity of a thin partition wall 26 that separates the passage 25 froman overlying, small receiving chamber 2'! for soda water under highpressure. Extending through and fixed in this partition wall is a nozzle28 of very small bore. When soda water under high pressure enters thechamber 2'! it can escape only through the small nozzle 28 which acts asa pressure reducer. Therefore, the soda water that enters the passage 25has a relatively low pressure. The nozzle 28 is coaxial with and extendsinto the tubular stem 23, so that soda Water discharged from this nozzlepasses down through the interior of the valve stem. That part of the thevalve 2I is enlarged to form an expansion chamber. The soda water leavesthis chamber through small holes 29 in the cylindrical wall of the stem.The valve 2| has a deep, depending skirt 30 of large diameter, extendingdown below the level of the lowermost of the openings 29, so that thedischarged soda water strikes the inner surfaces of this skirt and thenfiows downwardly along the same. While this is taking place, if thevalve 2| is open, syrup flows down along the outer surfaces of the skirtand mingles with the soda water at the extreme lower edge of the skirt.

The valve 2| is normally held closed by a strong coil spring 32'surrounding the valve stem and the part 24 below the valve. The upperend of the spring engages with the under side of the valve, and thelower end of the spring rests on the horizontal arm of a bracket 33fixed to the casing 2. The bracket is shown as depending from a shortsleeve 34 screwed into a short nipple 35 of large internal diameterdepending from and integral with the casing 2. This nipple, togetherwith the bracket and the parts supported by the bracket extends downinto the main nozzle 3 when the casing and the main nozzle are assembledas in Figs. 1 and 2; a liquid-tight joint between the casing and themain nozzle being obtained by employing a gasket 36 that underlies aflat surface 31 around the upper end of the nipple.

The soda water is delivered into the draft arm through a plug-like unitthat is set into the measuring chamber 1. This unit embodies a head 38and a tubular stem 39 much smaller in diameter than the correspondingdimensions of the head. The measuring chamber opens out through one sideof the casing. The parts are so proportioned that when the plug-likeunit is inserted, the head 38 fits in and closes the open end of thischamber. A fluid-tight joint between the head 38 and the surroundingwall of the measuring chamber is obtained through a radially expansiblegasket 40. In order that this gasket shall not be required to serve asthe means to hold the unit in place, I provide a pair of detachablemetal strips or cleats 42 which, as best shown in Figs. 5, 8 and 9, arefastened to the outer face of the casing 2 beside the open end of themeasuring chamber and in overlapping relation to the head 38, by meansof screws 43. Any outward pressure upon the member 38 is thereforeresisted by the strips or cleats 42.

The soda water enters the casing through a pipe 44, shown in Fig. 2,which is attached to a nipple 46 which opens into the space within thetubular stem 39. The inner end of the tubular stem is open andcommunicates with the chamber 21 so that, when free to do so, soda waterentering through the nipple 46 passes through the tubular stem, into thechamber 21, and down through the nozzle 28. Normally, entrance to thechamber 21 is shut off by a valve 41 arranged within the tubular sternand normally held against its seat 48 by a coil spring 49. A valve stem50 extends from the valve through the wall of the casing opposite thatat which the nipple 46 is located The plug valve 9 is adapted to beturned and the valves 2| and 41 to be opened by manipulation of thehandle 4 as will now be described.

Fixed to the thickened front wall 52 that closes one end of the plugvalve 5 is a radial arm 53 having a slot 54 cut into the same throughthe upper edge, and provided with a laterally projecting boss 55. A link56 has one end entered in the slot 54, extends forwardly through anopening a in the front wall of the receptacle A, and is connected at itsfront end to the operating handle, as indicated at 51. The link 53 is athin, wide bar-like element arranged on edge so that the opening a inthe wall of the receptacle need be little more than a slit. The innerend of the link is fastened to the radial arm 53 by a pin 58 extendingthrough the boss and across the slot in the arm, as best shown in Fig.5. The pin has on the forward end a head 59 which is in the form of athimble fitting around the boss 55 and serving as a head by which thepin may be manipulated. The pin is smooth at the inner end thereof andis provided with a screw threaded section 60 at the head end. Theexternal diameter of the threaded portion of the pin is no greater thanthe diameter of the smooth portion, and the parts are so proportionedthat by turning the head on the pin the latter may be shifted from theworking position shown in Fig, 1 to a release position in which itstands retracted clear of the slot 54, but cannot be completelyunscrewed from the arm.

On the front end of the plug valve are two cam devices. As best shown inFig. '1, one of these cam devices comprises a pair of lugs orprojections 62 and 63 on the periphery of the wall 5?; of the plug,these lugs or projections being on the under side of the valve. Theselugs or cam elements are adapted to cooperate with a cam roller 64 onthe cross bar 65 of a device by which the valve H is opened. This valveopening device may conveniently consistof the cross member 65 and twostiff rods 56 fixed thereto and extending down through a thickened partof the casing 2 into engagement with the top of the valve 21. With thisarrangement, the valve iii may be opened by shifting the operatinghandle either to an extreme forward position or into its rearmostposition.

The second cam device is a face cam on the front face of the wall 52 ofthe plug; this face cam having a long fiat section 61 arranged. at rightangles to the axis about which the plug valve turns and an inclinedsection 53 at one end of the flat section. This face cam is adapted tocontrol the valve 41.

As best shown in Fig. 5, there is mounted on the front end of the bodyof the casing a rocking lever 69 whose lower end lies just in front ofthe front end of the valve stem 58 and whose upper end carries a camroller 19 in position to engage the face cam on the plug valve. Theparts are so proportioned that whilethe flat part of the face cam liesopposite the roller 163, the rocking lever does not touch the end of thevalve stem 50, so that the valve 41 is held closed by its spring 49,When the cam roller rides up upon the inclined section 68 of the facecam, the lever 59 is rocked and its lower end forced rearwardly so as topush against the end of the valve stem 58 and force the valve 41 open.

There is a long coiled spring 12 fastened at one end to the front end ofthe plug valve 9, and at its other end to a fixed part of the casingwhich tends constantly to hold the plug valve at one limit of its rotarymovement, which corresponds to the rearmost position of the operatinghandle 4. The greater portion of the spring 12 is housed within astationary sleeve 13. Actually what the spring 12 does is normally tohold the plug valve in the angular position illustrated in Figs. 6 and'1, wherein the cam lug 62 engages with the cam roller 64. In otherwords, the tendency of the spring 12 is to turn the plug valve farenough to cause the cam element 62 to force the cam roller 64 down andopen the valve 2|. However, the valve spring 32 is stronger than thespring 12 and therefore the cam roller 64 simply acts as a stop for thecam lug 62, and the valve 2| does not open. However, when the operatinghandle is pushed rearwardly from its neutral position, it assists thespring 12 to overcome the resistance of the valve spring 32, andtherefore the valve 2| may be caused to open by pushing the operatinghandle back as far as it will go, This condition is illustrated in Fig.12. When the operating handle is drawn forward as far as it will go, thecam lu 63 engages with and rides up on the cam roller 64, as illustratedin Fig. 11, and the valve 2| is opened. During this forward movement ofthe handle, the inclined portion 68 of the face cam engages with the camroller 10 and rocks the lever 69 so that at the time the cam lug 63forces the syrup valve 2| open, the cam section 68 causes the soda watervalve 41 to be opened. In other Words, when the operating handle isdrawn into its forward position, both syrup and soda water will bedelivered, whereas when the operating handle is pushed into its rearwardposition, only the syrup valve is opened, the soda water valve remainingclosed.

Figs. 8, 15 and 16 illustrate the three positions of the plug valvewhich correspond to the three positions of the operating handle justdescribed. In Fig. 8 the plug valve is in the neutral position,corresponding to the positions of the parts in Fig. 7, at which timeboth the valve 2| and the valve 41 are closed. Now the ports 8 and IDare in registration with each other, permitting syrup to flow down fromthe plug valve and fill the measuring chamber which is shut off fromdirect communication with atmosphere, so that the air in the measuringchamber which is displaced by the syrup must pass out through the plugvalve as heretofore explained. When the operating handle is drawnforward into its dispensing position, illustrated in Fig. 11, the plugvalve assumes the position shown in Fig. 5, wherein the port I0 isdisplaced angularly from the port 8, and the port 8 registers with thevent passage l3 which in turn registers with the vent outlet |2 in thecasing. Thus, while syrup and soda water are being dispensed, air mayenter the measuring chamber to displace the syrup.

When it is desired to drain or flush the apparatus and the operatinghandle is pushed back into its rearmost position, as in Fig. 12, theplug valve is shifted only slightly from the neutral position of Fig. 8to assume the position illustra-ted in Fig. 16; the ports 8 and |0 beingin partial registration with each other and the measuring chamber beingshut off from the vent passage l3. Consequently, while the plug valveremains in this position, the syrup valve 2| being open, liquids canflow by gravity from the syrup container through the draft armapparatus, and out through the main nozzle 3.

Since the draining or flushing of the apparatus front wall of thereceptacle A just above the link 56 and having a slot 15 cut into thesame from the lower edge in the plane of this link. The parts are soproportion-ed that when the plate 14 is swung down as shown in Figs. 1and 4, the slotted end of the late straddles the link and forms a stopdirectly behind the elbow 16 of the operating lever through which thehinge pin 51 extends; the plate therefore apparatus, the plate therelease position in Fig. 1, leaving the dispensing receptacle. In thearrangement shown, the base plate 11 is provided with a pair offorwardly projecting parallel ears 18 between which the lower end of theoperating lever lies. A horizontal hinge pin 19 extends through theseears and through the intervening portion of the operating lever. At theupper end of the base zontal hinge pin 8| paralleling the hinge pin 19.

The present invention contemplates also various more or less minor butvery useful structural details. One of these has to do with the mannerof securing together the casingZ for the valve mechanism and the mainnozzle. The casing has a detachable cover 82 over region water valve arelocated. This cover is held in place by a tubular bolt 83, best seen inFigs. 5 and 6; there being a nut 84 on one end of this through thetubular bolt 83 and into the boss 85. 86 is a head or Another usefulfeature has to do with the securing together of the valve casing and thesyrup container. The open end of the chamber 6 that contains the plugvalve, as best shown in Fig. 5, has a frusto-conical seat 88 againstwhich rests a rubber gasket 89 on the lower part of the elbow H whichprojects slightly into the said chamber. The elbow has thereon anannular in the casing. outwardly opening socket 9| coaxial plug valve.Depending from the container at a distance from the elbow |1 slightlygreater than the length of the valve casing, is a bracket 92. Thisbracket carries a horizontal screw bolt 93 whose free end is adapted tobe entered into the socket 9| in the casing after the lower arm of theelbow H has been inserted in the open tightening 82 is an, with thepiece or head turned. It will thus be seen that the valve casing and thesyrup container may be fastened together or disconnected from each otherby operating a single screw bolt which may be turned by simply takinghold of the head in ones fingers.

Positive stops may be provided for limiting the turning movements of theplug valve in either direction and, therefore, the swinging movements ofthe operating handle. As best shown in Fig. 12, there is a stationarylug 95 below a crescentshaped piece 96 fixed to the forward end of theplug valve in front of the cams 62 and 63. When the plug valve is in thedraining or flushing position, as in Fig. 16, the lefthand horn of thecrescent is in contact with the stop lug 95 as shown in Fig. 12. Whenthe handle is pulled forward, the righthand horn of the crescent strikesthe stop lug as is apparent from Fig. 11.

While I have illustrated and described with particularity only a singlepreferred form of my invention, I do not desire to be limited to theexact structural details thus illustrated and described; but intend tocover all forms and arrangements which come within the definitions of myinvention constituting the appended claims.
